We've got them too:
The Kingston Parakeets, also known as the Twickenham Parakeets, are feral Rose-ringed Parakeets (Psittacula krameri) that live in the suburbs around Kingston and Twickenham, South London, England, numbering at least 6,000, with some estimates as high as 50,000 individuals[citation needed]. The origins of the flocks are subject to speculation.
No-one seems to know where they came from:
The specific origin of the birds is not known, but they most likely came from a single pair of breeding parakeets which escaped or were released in the mid-1990s. Other origins have been attributed to them: the most popular idea being that they escaped from Ealing Studios, West London, during the filming of The African Queen (which was actually made in the Isleworth Studios) in 1951. Other theories are that they escaped from an aviary during a 1987 hurricane;
...but I like this one best:
or that a pair released by Jimi Hendrix in Carnaby Street, London, in the 1960s, are to blame.
